Rapheal Davis scored 22 points and Purdue ran away from Missouri in the first half for an 82-61 win over the Tigers Tuesday in the Maui Invitational loser's bracket.

Coming off a tough loss to Kansas State in its opener, Purdue (4-1) was sharp at both ends against the young Tigers while building a 25-point halftime lead.

The Boilermakers struggled at times during the second half, but were so far in front that it didn't matter.

Missouri (2-3) had no answer for Purdue's physical, aggressive defense in the first half while falling into a big hole. The Tigers played better over the game's final 10 minutes, but had no chance of finishing off the comeback from a deficit that climbed to 34 points in the second half.
